From 1922b0f2758badc0b971d1ebbd300bc6635a6aef Mon Sep 17 00:00:00 2001 From: AnilKumar Ch Date: Mon, 13 Aug 2012 20:36:05 +0530 Subject: mfd: Move tps65217 regulator plat data handling to regulator Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

Fix it by removing all the checks for iTCO_wdt to keep the same behavior as 3.4 kernel. https://bugzilla.kernel.org/show_bug.cgi?id=44991 Actually the same check could be removed for the gpio-ich in lpc_ich.c, but I'm not sure if it will cause problems.

This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.
